The equation for the area of a triangle is 1/2 x base x height.
Plug in the values that you already have with h being the missing height value:
30= 1/2 x 12 x h
Simplify:
30=6h
Solve:
30/6=h
5=h
The heoght of the triangle is 5 units
Answer: 
Step-by-step explanation:
According to the empirical rule, the 95% confidence interval for the true population proportion is given by :-

Given : . The survey resulted in a sample proportion of p′=0.14, with a sampling standard deviation of σp′=0.02, who preferred reading an e-book.
Then, the 95% confidence interval for the true proportion of adults who prefer e-books will be :-

Hence, the 95% confidence interval for the true proportion of adults who prefer e-books=

Answer:
x = 1
Step-by-step explanation:
<u><em>since the function ln is the inverse of the function exponential then :</em></u>

By taking x as subject the formula becomes x = (v² - u²)/2a.
<h3>What is Equation?</h3>
An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.
Here given equation:
v² = u² + 2ax
2ax = v² - u²
x = (v² - u²)/2a
Thus, by taking x as subject the formula becomes x = (v² - u²)/2a.
